GRAIN-DRILL SPECIFICATION forming part of Letters Patent No. 665,047,dated January 1, 1901. Application filed m 13,1900. Serial No. 5,067.on; man.)

To (1,66 whom it may concern:

Be it known that I, ALBERT ARMITAGEfa citizen of the United States,residing at Fairport, in the county of Monroe, in the State of New York,have invented certain Improvements in Grain-Drills, of which thefollowing is a specification, reference being bad to the accompanyingdrawings.

My invention relates to certain improvements in grain-drills, whichimprovements are fully described and illustrated in the followingspecification and the accompanying drawings, the novel features thereofbeing specified in the claims annexed to the said specification.

In the accompanying drawings, representing a grain-drill embodying myimprovements, Figure 1 is a rear elevation. Fig. 2 is a partial planview of the divided axle. Fig. 3 is an elevation of the axle journal-boxas seen from the inside. Fig. 4 is a plan view of the journal-box. Fig.5 is an elevatioirof the clutches. Fig. 6 is a longitudinal section ofthe same. ble-faced driven member of the clutch. Figs. 9 and 10represent one of the driving members. Fig. 11 is a side view of thecasing surrounding the clutches. Fig. 12 is a rear view of the same.

A A represent the ground or carrying wheels, B B the sections of thedivided axle,

' and O the housing or casing surrounding the clutches.

D is the hopper, to which is attached the seed-distributing mechanism,which may be of any usual or preferred type.

E is the counter-shaft, which is rotated by gears ora chain andsprockets from the driven member F of the clutches. The counter-shaft isarranged to operate the grain-feeding mechanism G, being provided with aclutch and gears or chain to operate the grain-shaft H.

I represents one of the hoes, which may be of any preferred number,corresponding with the feeding devices. The hoes are of any ordinary orpreferred construction, and any suitable mechanism is employed forraising, lowering, or shifting them. The drill may also be provided withany suitable fertilizer attachment. Suitable mechanism may be cm- Figs.7 and 8 represent the douployed for varying the rate of the feed of thegrain.

.J represents the frame or, as it is usually called, the bed. Itconsists of a suitable bar of metal, bent backward at each end andhaving the brackets K attached at the corners, which brackets carry theadjustable or self-lining journal-boxes L. The axle-sections passthrough these journal-boxes. The brackets are provided with openingsthrough which the boxes are inserted.

The drill is provided with any suitable framework, to which the bed isattached.

At their inner ends the axle-sections are provided with the clutches NN, which ongage with the double-faced clutch member F. The constructionwill be understood from Figsq5 and 6.

P P represent flanged collars or bosses fastened on the ends of theaxle-sections, so as to rotate therewith. The driving members N N of theclutches are located within the flanges Q Q of the collars, beingprovided with ribs R, which engage with slots in the flanges, so thatthe clutch members are caused to rotate with the collars, while beingleft free to slide lengthwise to engage with or disengage from the teethS on the driven member F. Suitable springs T T" are employed to urge thedriving members toward the driven member. The teeth on the dilferentmembers of the clutches are made of any suitable shape and number,adapted to drive the central member from either axle section. The drivenmember F is provided with a ring of teeth or gear U, which engages withthe gear Von the counter-shaft E. When atany time during the operationof the drill the wheel A revolves faster than A, the clutch N will drivethe central member F, the member N yielding outward on its spring andits teeth slipping over the teeth of the driven member. A similaroperation takes place when the wheel A revolves faster than the wheelA', the clutch N antomaticaliy disengaging itself from the drivenmember. In this way provision is made for keeping the grain-feedingmechanism continuously in operation from This arrangement also preventsthe wheels I from rubbing against the ends of the hopper; as frequentlyhappens from the spring or wear of a straight axle.

The housing or casing C is attached to the bed and projects rearward, soas to support the inner ends of the axlesections and to inclose thegearing. The casing may be made in two or more parts separable from eachother, as shown. The collars P P revolve within suitable is alsoprovided with bosses/which support the counter-shaft.

I claim- 1. The combination with the mechanism of a grain-drill, of thedivided axle, the carrying-wheels, and means for operating theseeddistributing device from either portion of the axle, said meanshaving a sliding connection with the axle to permit variable speeds ofthe parts thereof without interfering with the operation of theseed-distributer.

bosses on the casing, which a grain-drill, of a dividedaxle, carryingwheels attached thereto, a clutch member to operate theseed-distributer, and means to drive said clutch member, comprisingmembers codperating with said clutch member and each having a slidingconnection with one of the axle-sections, substantially as described 3.In combination with the mechanism of a grain-drill, of a divided axle, aclutch memher to operate the seed-distributor, members cooperating withsaid clutch member, said latter members havinga sliding connection awith the axle, and springs for holding said latter members normally inoperative situation with the clutch' member.

4. The combination with the mechanism of a grain-drill, of a dividedaxle,a driven clutch member to operate the seed-distributor, drivingclutch members to codperate with the driven clutch mem ber, collarsattached to the axle sections, said driving clutch members having asliding connection with the collars.

5. The combination with the mechanism of a grain-drill, of a dividedaxle,a driven clutch member to operate the seed-distributor, drivingclutch members to cooperate with the driven clntch member, collarsattached to the axle-sections, said driving clutch members having asliding connection with the collars, and springs for normallymaintaining codperative situation of the driven and driving clutchmembers.

ALBERT ARMITAGE.
